[0017] The utility model will be further described below in combination with the drawings:

[0018] Referring to the drawings Figs. 1-2 In this embodiment, a locomotive rear tail box comprises a lower box body 1 and an upper box body 2, linkage assemblies 3 are installed on the outer walls of the lower box body 1 and the upper box body 2 and the left part, the lower box body 1 and the upper box body 2 form the main body structure of the locomotive rear tail box, a handle 5 is processed on the lower right part of the upper box body 2, the upper box body 2 is connected to the upper part of the lower box body 1, and buckle edges 4 are processed on the outer walls of the connection parts of the lower box body 1 and the upper box body 2.

[0019] Referring to the drawings Figs. 1-2 In this embodiment, the linkage assemblies 3 comprise support rods 3a1, springs 3a2, bases 3a3, blocks 3a4 and inclined rods 3a5;

[0020] The base 3a3 is fixedly connected to the left end of the lower box body 1, the inside of the base 3a3 is rotatably connected to the supporting rod 3a1 through a pin shaft, the upper end of the supporting rod 3a1 is fixedly connected to the upper box body 2, the lower rotating part of the supporting rod 3a1 is provided with a spring 3a2, the spring constant of the spring 3a2 can be determined according to the specific use, the two sides of the spring 3a2 are fixedly connected to the base 3a3 and the supporting rod 3a1 respectively, a plurality of inclined rods 3a5 are located on the front and rear sides of the lower box body 1 and the upper box body 2 respectively, the inner sides of the inclined rods 3a5 are rotatably connected through pin shafts respectively, the outer sides of the inclined rods 3a5 are rotatably connected to the lower box body 1 and the upper box body 2 through pin shafts respectively, and the inner right ends of the inclined rods 3a5 in the up-down direction are fixedly connected with the stop blocks 3a4, the stop blocks 3a4 can be used to limit the limit angle of the inclined rods 3a5, and the center points of the plurality of inclined rods 3a5 in the buckling state are consistent with the sticking positions of the lower box body 1 and the upper box body 2;

[0021] Through the cooperation between the handle 5, the upper box body 2, the lower box body 1, the spring 3a2, the inclined rod 3a5 and the stop block 3a4, the handle 5 is manually actuated to drive the upper box body 2 to rotate, so as to realize the rotation opening and closing between the upper box body 2 and the lower box body 1. However, in the process of opening and closing the traditional trunk, since there is no additional connecting structure between the upper and lower box bodies, the opening and closing state of the trunk can only be maintained by the friction of the rotating part or by manually holding the position of the upper box body 2. However, this process has the problem that the opening and closing state cannot be maintained due to insufficient friction or hand fatigue after long-term use. Therefore, the spring 3a2, the inclined rod 3a5 and the stop block 3a4 are designed. When rotating, the user can manually push the handle 5 to make the upper box body 2 rotate, at the same time, drive the two inclined rods 3a5 to rotate to a parallel state, and then manually push the connection part downward to the left. At this time, the connection part of the inclined rod 3a5 will move to the left and down and finally be clamped by the stop block 3a4 to maintain the opening and closing state of the trunk for a long time, effectively avoiding the problem that the opening and closing state cannot be maintained due to insufficient friction or hand fatigue after long-term use.

[0022] Working principle:

[0023] When the motorcycle needs to use the tail box, first, the user can assemble the whole structure according to the figure, after the assembly is completed, the bottom of the lower box body 1 can be installed at the corresponding rear structure of the motorcycle, when in use, the user can manually pull the handle 5 to drive the upper box body 2 to rotate, so as to realize the rotation opening and closing between the upper box body 2 and the lower box body 1, however, in the process of opening and closing of the traditional tail box, since there is no additional connecting structure between the upper and lower box bodies, it can only be realized by the friction of the rotating part or by manually holding the position of the upper box body 2 to maintain the opening and closing state of the tail box, this process has the problem that the opening and closing state cannot be maintained due to insufficient friction or hand fatigue after long-term use, therefore, the spring 3a2, the inclined rod 3a5 and the stop block 3a4 are designed, when rotating, the user can manually push the handle 5 to make the upper box body 2 rotate, at the same time, drive the two inclined rods 3a5 to rotate to the parallel state, then manually push the connection part to the lower left, at this time, the connection part of the inclined rod 3a5 will move to the lower left and finally be clamped by the stop block 3a4 to keep the opening and closing state of the tail box for a long time, effectively avoiding the problem that the opening and closing state cannot be maintained due to insufficient friction or hand fatigue after long-term use, after completing the storage of the goods in the tail box, only need to push the upper box body 2 upward and the connection part of the inclined rod 3a5 to the right upward, the original buckling state can be restored.

[0024] Although the utility model has been illustrated and described by referring to the preferred embodiments, it should be understood by those skilled in the art that various changes in form and details can be made within the scope of the claims.
